In this work, a tribological performance analysis is numerically conducted for a surface‐textured ring‐deformed liner conjunction. In the analysis, three different distribution patterns of surface texture are designed and machined on the surface of ring. To evaluate the frictional properties of the textured rings under mixed lubrication regime, a transient lubrication model considering the oil film thermal effect is developed. Meanwhile, to evaluate the oil film consumption and the transition of lubrication condition in an engine cycle, an oil transport model is built to determine the boundary positions of lubrication zone. Based on the models, the oil consumption, MOFT (minimum oil film thickness), friction force, power loss, and FMEP (friction mean effective pressure) value of the textured ring are studied under different oil supplies. The frictional characteristics of the rings with various distribution patterns of surface texture are also analyzed and compared. The results show that the edge‐textured ring can improve the tribological performance significantly, and the improvement varies with the oil supply.

不同供油条件下表面织构对改善环形变形内衬接头摩擦性能的影响

在这项工作中，对具有表面纹理的环形变形衬管接头进行了摩擦性能分析。在分析中，设计并在环的表面上加工了三种不同的表面纹理分布模式。为了评估网纹环在混合润滑条件下的摩擦性能，建立了考虑油膜热效应的瞬态润滑模型。同时，为了评估发动机循环中的油膜消耗量和润滑条件的变化，建立了一个输油模型来确定润滑区的边界位置。基于这些模型，研究了在不同供油条件下网纹环的耗油量，MOFT（最小油膜厚度），摩擦力，功率损耗和FMEP（摩擦平均有效压力）值。还分析和比较了具有各种表面纹理分布模式的环的摩擦特性。结果表明，边缘织构的环可以显着改善摩擦性能，并且该改善随供油量的不同而不同。
